To all whom t may concern.'

Be it known that l, GEORGE B. OWENS, a citizen of the United States, residing at Merriam, in the county of Johnson and State of Kansas, have invented certain new and useful improvements in Display-Cabinets, of which the following is a speciiication.

My invention relates to portable display cabinets, and my object is to provide a compact cabinet of this character whereby a large number of maps, charts, etc., can be displayed.

The cabinet is particularly adapted for use in schools and other educational institutions, as it can be readily moved to any location in a school room, and while compact in form has a large capacity for maps, charts, and other display sheets. It also has one or more surfaces which may be used as a blackboard.

In order that the invention may be fully understood, reference will now be made to the accompanying drawings, in which:

Figure 1 is a perspective view of a cabinet embodying my invention. Fig. 2 is a cross section of the upper portion of the cabinet and a spring-actuated roller therein, taken on line II-II of Fig. 1. Fig. 3 is a vertical section on line Ill-Hl of Fig. 1, with one of the maps or charts exposed. Fig. l is a broken front elevation of the cabinet with the front door thereof in open position.

In carrying out the invention, l employ a vertical case 1, made, preferably, of sheetmetal and comprisinga rear wall 2, semicircular top and bottom walls 8 and l, respectively, side walls 5, a narrow front wall 6, and a door 7, which latter yis mounted on hinges 8 just above the front wall 6.

The front wall 6 stops short of the bottom wall et to leave a transverse slot 9, and the door 7 stops short of the top wall 3 to leave a transverse slot 10. Door 7 is provided with two vertical marginal flanges 11 to add rigidity thereto and to lap the side walls 5 to exclude dust from the interior of the cabinet. TheI flanges 11, also grip the side walls 5 with sufficient friction to hold the door 7 in closed position.

The side wall 5 at the left of the cabinet is reinforced by an interior wall 12, having downwardly inclined superimposed slots 13 therein, Fig. 3, to admit the trunnions 14C at the left end of a plurality of rollers 15 carrying maps, charts or other display sheets 16, each secured at its inner end to its respective roller 15 and provided at its outer end with a transverse metallic strip 17.

Each roller 15 is provided at its right end with an enlarged trunnion 18 having a rec-I tangular socket 19, to receive the corresponding end of a crank 20, whereby the roller may be rotated to wind its respective display sheet 16 thereon.

Journaled in front of each roller 15 is a small guide roller 21, and j ournaled in bearings 7EL at the upper edge of the door 7, is a small antifriction roller 22 for the display sheets to run over, as will hereinafter appear.

23 designates a take-up roller having one trunnion journaled in the interior wall 12 and its opposite enlarged trunnion 24 journaled in the wall 5 at the right side of the cabinet.

Trunnion 24 like trunnions 18 has a rectangular socket 19 to receive the rectangular end of the crank 20. Roller 23 has a longitudinal slot 25,011@ margin of which is bent inward slightly as indicated at 26 to forni a iiange for engaging the metallic strips 17 of the display sheets 16, see Fig. 3.

27 designates a spring-actuated roller journaled in the upper portion of case 1, upon a stationary shaft 28. Roller 27 is yieldingly-connected to the stationary shaft 28 by a coil spring A9, which automatically rotates said roller to wind thereon a map or chart, or other display sheet 30.

rlfheinner end of the display sheet 30, is secured to the roller 27 and its outer end to a transverse rod 31, which is longer than the l slot 10, so that the ends of said rod will abut the front edges of the side walls 5 and thus prevent the free end of the display sheet 30 from being drawn inward through said slot 10 by action of the spring 29.

VThe display sheet 30 is, preferably, shorter than the display sheets 16, and consequently can be wound its full length upon the roller 27 through the intermediacy of the spring 29, but if the display sheets 16 are to be no longer than the display sheet 30, it is obvious that the rollers 15 may be provided with springs 29 to be rotated thereby instead of the crank 20. I have found in practice, however, that the crank 2O is preferable to a spring for winding long display sheets upon the rollers.

32 designates a pair of-hooks secured to the front wall 6 near its lower corners, to receive the projecting ends of rod 31 when the display sheet 30 is drawn downward so that the cabinet can be readily movedaround to the most advantageousposition in a school room for displaying lthe maps or charts.

The back legs 33 .have upward extensions 35 to brace ,the rcabinet and support it ,in vertical position. The front and back legs are secured together by bolts 36 and to the cabinet by bolts 37, so that they can be readily removed from said cabinet and taken apart preparatory to shipping or storing the cabinet in its most compact form. When it is desired to expose the display sheet 3.0, it is only necessary to grasp its outer ,end and draw it .down into engagement with the hooks 32. To roll up said display sheet, it is only necessary to release the rod 31 when the spring 29 will rotate the roller 27 until the projecting ends of said rod 31 contact the ends of the slot l0, as shown on Fig. 4. V

When it is desired to expose any of the display sheets 16, door 7 is lowered to gain access to the free end of the desired sheet, which is drawn forward beneath its respectiveI guide-roller 21, thence upward over roller'22, after which the Adoor 7 is closed. The end of the display sheet is then pulled downward over the front of case l and its marginal strip 17 is placed through the slot 25., in roller 23, and into engagement with the marginal iiange 26, Fig. 3. Roller 23 is then rotated to wind thedisplay sheet thereon, through the intermediacy of the crank 20. To wind the display sheet 16 `back upon `its respective roller 15, it is only necessary t0 TOM@ Said 101161" in the proper direction through the intermediacy of the crank 20.

The front and back of the case 1, are, preferably, Prepared as blackboards, which may be used when the display sheets are wound upon their respective rollers.

From the foregoing description, it is ap- Uopies of this patent may be obtained for rive cents each, by addressing the parent that I have produced a display cabinet having a large capacity for maps, or charts, or other display sheets, and which is compact, strong and durable, and while I have shown the preferred form of my in vention, I reserve the right to make such Kchanges in proportions, arrangement, and

.combination oi parts as properly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A display cabinet consisting of a case, superimposed rollers mounted in said case having display sheets wound thereon, an antifriction roller near one end of the case for said display sheets to run over, a. takeup roller in the opposite end of the case adapted to engage the free end of each display sheet and wind the latter thereon, said superimposed rollers being mounted intermediate said antifriction and said takeup rollers, said case being provided with'slots adjacent said antifriction roller and said take-up roller through which said display sheets are adapted to pass, and a door at the front of the case normally covered by one of said sheets whereby access may be gained to any of the display sheets.

v2. A display cabinet consisting of a case, a roller mounted in said case, a display sheet secured at one end to said roller and having a normally free end, a strip secured to the free end of said display sheet, and a take-up roller having a longitudinal slot, one edge of said slot being turned inwardly to form a fixed internal flange said flange being adapted to engage the strip on the display sheet preparatory to winding the latter upon the take-up roller.

In testimony whereof I affix my signature, in the presence of two witnesses.
